AIR-PURI FIER.

SPECIFICATION forming part of Letterslatent No. 266,267, dated October 24, 1882.

Application filed April '7, 1882. I (No model.)

To all whom it may concern:

Be it. known that I, PETER BREEN, a citizen of the United States, residing at Cincinnati, Ohio, have invented new and useful Improvements in Air-Purifying Apparatus, of which the following is a specification.

My invention relates to devices to be used for the purpose of purifying and cleansing air from particles of dust, 850., held in suspension therein, and may be applied with advantage to the discharge-conduit of the air-blast used for conveying shavings, &c., to the boilerroom in furniture-factories, and the like. In such and similar factories it is common to employ a blast of air, conducted in suitable tubes, as the moving force for conveying shavings, chippings, and other fine refuse used as fuel for generating steam into a common receptacle or chamber adjoining the furnace, whence the air is permitted to escape through proper outlets to the outside. In this case, however, the escaping air is charged with particles of sawdust, fine shavings, &c.,which, besides being a nuisance to persons passing by or working in the vicinity, settle over out-buildings, lumber, 850., thus covering them with a highlydangerous deposit of inflammable material in its most combustible form. These objections my invention is designed to remedy; and to this end it consists in the construction and arrangement of apparatus, as hereinafter more fully set forth.

My invention is exhibited in the accompanying drawings, in which Figure 1 is a cross-sectional elevation of the water-box and its deflecting-partitions, taken through the plane of m m, Fig. 2; and Fig. 2 is a plan view of the water-box complete.

The apparatus exhibited in the drawings is' designed to be used at the outlet end of the air-conduit leading from the shaving-room of furniture-factories, planing-mills, and the like,

- but, as will be obvious, it may be used in connection with the ventilating air-inlets of railway-cars, flouring-mills, &c.

A in the drawings designates a water box or trough, of any convenient length and size, into which enters the air-conduit B. Water is kept in the trough at a convenient height, and in front of the mouth of the air-conduit B, and extending downward to near the level of the mobility of the latter, is forced beyond the partition a. As the water tends to seek itslevel it tends to flow back into the depression thus formed beneath the end of the partition (I, and

by this action the water is sprayed and thrown upward by the air-currents against the under side of the partition I), whence it flows downward and drips from the lower end of partition 1) across the intervening space upon the partition to, and thence from its lower end across the air-space to the body of liquid in the trough. The course of the air is indicated by the arrows.

My invention is operative and useful to apracticable degree with only the apparatus above described; but it will be obvious that the principle involved in the arrangement of the partitions so as to catch and drip the water across the air-channel may be extended to any number of partitions thus arranged. In practice I find it desirable to add a third deflecting-partition, 0, arranged above the first and extending far enough to drip upon the second partition I). A deflector, f, may also be arrranged to exhaust the airinaparticular direction when necessary.

WVhere a constant supply of water can be hadas from city mains or any other source of supply-it is desirable to provide for maintaining the water in the trough at a uniform level and restore the loss by evaporation. To this end the ordinary float-regulator may be used and attached to a stop cock upon the supplypipe.

In order to afford means of cleaning the trough from the accumulation of trash, the upper and front portion, (1, of the trough or box is removably attached by hinges, as shown, so as to be readily opened, and is secured by a hook and staple or some other convenient fast- I to catch the water-particles anddrip them across ening. the air-passage, substantially as set forth.
